5.4 ELECTRICAL CONNECTION OF THE INDOOR UNIT
CAUTION
Check to ensure that the eld supplied electrical components (ma-
ins power switches, circuit breakers, wires, connectors and wire
terminals) have been properly selected according to the electrical
data indicated on this chapter and they comply with national and
local codes. If it is necessary, contact with your local authority in
regards to standards, rules, regulations, etc.
5.4.1 Wiring size
Use wires which are not lighter than the polychloroprene sheathed
exible cord (code designation 60245 IEC 57).

CAUTION
• Ensure specically that there is an Earth Leakage Breaker
(ELB) installed for the units.
• If the installation is already equipped with an Earth Leakage
Breaker (ELB), ensure that its rated current is large enough to
hold the current of the units.
NOTE
• Electric fuses can be used instead of magnetic Circuit Break-
ers (CB). In that case, select fuses with similar rated values
as the CB.
• The Earth Leakage Breaker (ELB) mentioned on this manual
is also commonly known as Residual Current Device (RCD) or
Residual Current Circuit Breaker (RCCB).
• The Circuit Breakers (CB) are also known as Thermal-Mag-
netic Circuit Breakers or just Magnetic Circuit Breakers (MCB).

5.5 TRANSMISSION WIRING BETWEEN OUTDOOR AND INDOOR UNIT
• The transmission is wired to terminals 1-2.
• The H-LINK II wiring system requires only two transmission cables that connect the indoor unit and the outdoor unit.

• Use twisted shielded pair cable or shielded pair cable for transmission wires between the indoor and the outdoor units, and connect
the shielded part (only one side) to the earth screw in the electrical box of the indoor unit.
• In the event that a conduit tube for eld-wiring is not used, x rubber bushes to the panel with adhesive.
CAUTION
Ensure that the transmission wiring is not wrongly connected to any live part that could be damaged the PCB.
5.6 SETTING OF REMOTE CONTROL SWITCH
This unit is factory set with the Optional Function: Output Signal
o2 02 “Alarm Signal” activated.

CAUTION
Make sure that this conguration is set after installing / wiring the
indoor unit. If not, set this Optional Function as indicated above.
